Freud RP-OPB 3-1/32” diameter Raised Panel Back-Cutters are precision-designed for the Freud/Diablo RP system. When paired with RP-A, RP-B, RP-C, RP-D, or RP-E knives on the RP1000 head, these back-cutters deliver clean, repeatable back-cut profiles that bring your raised-panel cabinet doors to life with confidence.

Key capabilities

• Enables use of 3/4" to 13/16" thick panels while maintaining a consistent 1/4" tongue—ideal for standard raised-panel door construction without sacrificing panel fit.
• Back-cut geometry finely tunes shoulder clearance, reducing tear-out and ensuring smooth, flat panel faces even on medium-density materials.
• Designed to work seamlessly with RP-A, RP-B, RP-C, RP-D, and RP-E knives on the RP1000 head, streamlining your current tooling setup.
• Optimizes your workflow for cabinet shops and hobbyists building traditional raised-panel doors, craft furniture, and intricate paneling.

Ideal uses and applications

Perfect for creating durable raised-panel cabinet doors in kitchens, baths, and furniture pieces. If your project calls for a classic, elegant panel profile with crisp edges and a uniform tongue, the RP-OPB back-cutters help you achieve professional results with fewer passes and less material waste.

Why this back-cutter matters

Rather than relying on generic back-cutting methods, the RP-OPB set is tuned for compatibility with the RP1000 head and RP-series knives, delivering consistent tongue dimensions across a range of panel thicknesses. This translates to tighter door gaps, steadier panel fit, and a finish you can trust on every run.

Practical tips for best results

• Install the appropriate RP-A through RP-E knife on the RP1000 head before mounting the RP-OPB back-cutters.
• Set your depth to achieve a precise 1/4" tongue on the rail to ensure a tight, functional joint with the stiles.
• Always test on scrap material that matches your project to verify fit and finish before committing to production runs.
• Feed direction and cut sequence should prioritize clean back-cut engagement to minimize tear-out, especially on figured woods.

Who benefits most

Woodworkers, cabinetmakers, and DIY enthusiasts who routinely build raised-panel doors and panels will appreciate the reliable, repeatable results, reduced setup time, and compatibility with existing Freud/Diablo RP tooling. If your goal is a high-end, architectural-grade panel look with consistent tongue dimensions, the RP-OPB back-cutters are a strategic upgrade for your RP system.
